New glue offers to turn any small walking robot into Spider-Man
To climb walls, robot feet need to alternately stick and let go. A novel adhesive can do that. Its stickiness is controlled by electric fields.
- Chemistry
Lots of makeup may contain potentially harmful ‘forever chemicals’
Hints of PFAS compounds have turned up in about half of tested makeup products. Waterproof mascaras and lipsticks were very likely to contain them.
- Physics
Nuclear clocks are nearly here
More precise clocks could improve technologies such as GPS and help scientists test major ideas in science.
- Chemistry
Sleep-friendlier lighting is on the way
Chemists have created a new glowing material for LEDs. It should lessen how much near-bedtime lighting impairs your ability to nod off.

Mantis shrimp inspires somersaults of new soft robot
Its rolling acrobatics allow this robot to move especially swiftly — much as a fictional new Disney character can.
- Chemistry
Copper ‘foam’ could be used as filters for COVID-19 masks
The lightweight new material could serve as a washable and recyclable, eco-friendly alternative for many current mask filters.
- Brain
Patterns in brain activity can identify who will struggle to read
Certain patterns of brain activity predict whether teens are strong readers or will struggle. Those diagnostic patterns show up even when doing math.
- Health & Medicine
Bandages made from crab shells speed healing
The chitin in seafood wastes, insect “bones” and fungi is a chemist’s dream. Used in a new medical dressing, it beats regular gauze for wound healing.

Scientists Say: Piezoelectric
Piezoelectric materials produce an electric voltage when they are bent or squished. This can let us harvest electricity from movement.
- Agriculture
Dew collector brings water to thirsty plants
This invention grabs water from the air at night. All it needs is the sun’s warmth the next day to release that moisture to growing plants.
- Chemistry
Bye-bye batteries? Power a phone with fabric or a beacon with sound
New piezoelectric systems produce electricity in unusual ways, such as when a certain nylon bends or underwater ceramics vibrate.
- Chemistry
A soil-based ‘concrete’ could make buildings green, even on Mars
A new soil-based material offers an alternative to concrete for 3-D printing environmentally friendly buildings.
